GHCN-Daily is a dataset that contains daily observations over global land areas. It contains station-based measurements from land-based stations worldwide, about two thirds of which are for precipitation measurements only (Menne et al., 2012). GHCN-Daily is a composite of climate records from numerous sources that were merged together and subjected to a common suite of quality assurance reviews (Durre et al., 2010).

The archive includes the following meteorological elements:

  • Daily maximum temperature
  • Daily minimum temperature
  • Temperature at the time of observation
  • Precipitation (i.e., rain, melted snow)
  • Snowfall
  • Snow depth
  • Other elements where available

In this archive, the period of record station files are parsed into yearly files that contain all available GHCN-Daily station data for that year plus a time of observation field (where available—primarily for U.S. Cooperative Observers).

The observation times for U.S. Cooperative Observer data come from the station history archived in NCDC’s Historical Observing Metadata Repository (HOMR).

The files are updated daily on AWS to be in sync with updates to the GHCN-Daily dataset at NOAA.
